Early on in Wings of Liberty, KiLLeR found little success, mostly hitting the spotlight as a 2v2 player for Team Dignitas in the EG Master's Cup alongside SeleCT. One notable exception for this would be his 2010 Blizzard Latin American Invitational 4-0 against Fenix, one month after his StarCraft II debut.

August 2011 turned out to be one of the most successful months for KiLLeR. He managed to place second at the Latin American Battle.net invitational, and qualified for BlizzCon 2011 StarCraft II Invitational. Later, he won the Chilean WCG qualifier, and qualified for WCG 2011. In October, KiLLeR managed to make it out of the group stages of IEM New York in second place behind the South Korean Killer. He managed to beat elfi in the playoff round 3-2 before losing to DongRaeGu in the semifinals 0-3. In the bronze match, KiLLeR faced off against Gatored and to secure a very respectable third place in the tournament by beating him 3-1.

At Blizzcon 2011, KiLLeR would lose to DIMAGA in the first round, 1-2. He would later beat Nifi and Sheth in the lower bracket before losing to Sen 0-2 in round three of the lower bracket.

At World Cyber Games 2011, held in Korea, in the group matches (they were all Bo1), had a record of 5-1, knocking down IdrA and finishing 2nd behind TitaN. In the play-offs he lost to Bling 1-2 finishing in Round of 16.
